In an article published in The Telegraph on Sunday, President Kersti Kaljulaid said that as President of Estonia, she represents the only truly digital society which actually has a state.

"Almost all our citizens' interactions with the government, including voting, can be done securely online, and our 'e-residents' can incorporate and run their businesses in Estonia without ever having to set foot here," Kaljulaid said.

"Seeing this digital revolution up close has made me question whether the state as we know it today is fit for the 21st century," she continued.

The Estonian president said that, traditionally, nations have harnessed taxpayers to their territory by making almost all social guarantees dependent on working in one country, every day, every month and for at least three decades.

"In creating the free movement of people, this web has only gotten more complex, but never disappeared," she explained. "It is the same old story of where you live, where you work equaling where you are entitled to get social benefits."
